Sender Framework Policy (SPF)

The video tutorial explains the Sender Policy Framework (SPF), a security mechanism to prevent email spoofing by verifying the sender's IP address against a list of authorized IPs in the DNS records. It illustrates scenarios with and without SPF, highlighting the importance of defining SPF records to ensure secure email delivery. The tutorial also guides on checking and configuring SPF records using tools like MX toolbox.

What is the primary purpose of the Sender Policy Framework (SPF)?

• Bob's server will deny the email delivery

• The email will be delivered without issues

What does Bob's server check to verify the authenticity of an email from Alice's server when SPF is defined?

• The SPF record and IP address

• The sender's email address

• The email subject line

• The email content

Why is it important to include third-party application IPs in your SPF record?

• To increase their email storage

• To allow them to send emails on your behalf

• To block them from accessing your server

• To encrypt their emails

Which tool can be used to check the SPF record of a domain?

• Domain Inspector

• Email Verifier

• MX Toolbox

• DNS Checker

What is the format version mentioned for SPF records in the tutorial?

• SPFv4

• SPFv1

• SPFv2

• SPFv3

What command is used to include authenticated servers from Google in an SPF record?

• include:google.com
